BILLING-PRESS.

To all whom it may concern Be itknown that I, Join: \V. Gixnwooo, a citizen of the United States, residing at Lawton, in the county of Comanche and State of Oklahoma, have invented new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to baling presses and. particularly to that class of presses which are equipped with mechanism for condensing the charge before the same is projected into the baling chamber forfinal compression.

The principal object of the invention is to produce a condensing device of simple and improved construction which is adapted to be applied to and used in connection with abaling press of ordinary or conventional construction.

A further object of the invention is to simplify and improve the construction and arrangement ofthe condensing chamber. A. further object of the invention is to simplify and improve the construction, arrangement and operation of the so-called condenser apron which constitutes one of the walls of the condensing chamber and which serves to compress or condense the charge within the chamber.

A' further object of the invention is to simplify and improve the arrangement and operation of the plunger whereby the condensing charge is projected within the baling chamber 111 advance of the main plunger head 26.

With these and other ends in wow which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

Corresponding parts in the several figures of the drawings are denoted by like characters of reference.

The improved baling press may be mounted on ground wheels a portion of one of which is shown at 15 in Fig. 1 for convenience in transportation. The main press box or press chamber is constructed with angle irons 17 at the corners thereof. 18 designates the tension screw and 19 the dogs or catches which are provided to prevent return of the compressed material. The side walls 20 of the condenser chamber are substantially sector-shaped as will be clearly seen in Figs. 5 and 6, said side walls extending across the top of the press box, being curved downwardly and outwardly at one side of the box. The condenser chamber has a stationary end wall 21, the other end modate the operating shaft 25. The main plunger head 26 which operates longitudinally in the ress box is connected by a rod or pitman 2 with a wrist pin 28 on the main driving wheel 29 which is supported for rotation and'which may be driven in any convenient well known manner by power derived from any convenient source. The stroke of the main plunger head should obviously be sufficient to carry material past the dogs 19 on the compression stroke and to carry the plunger from beneath the condenser chamber on the return or retracting stroke.

Guided for reciprocation vertically in the condenser chamber, adjacent to the side wall 21, is a plunger 30 having adjacent to the open side of the condenser chamber a vertically disposed upwardly extending shield ported for rotation adjacent to the upper edge of the end wall 121 has a radially extending arm or lever 33 which is connected with the plunger 30 by a link 34, whereby the plunger 30 may be moved vertically through :the condenser chamber. The parts, including the means for actuating the rock shaft 32 to be hereinafter described, are to be so arranged and proportioned that when the plunger is at the downward limit of its movement the pivot member 35, connecting the lever 33 with the link 34, -will pass slightly beyond the center of the line of thrust, thereby locking the plunger 3O temporarily in a down position. The side Walls 20 of the condenser chamber may be vertically grooved as .seen at 36 to provide guide ways for guide members 37 on the pl ngerfifl- Y I i The actuating mechanismfor the plunger 30-includes a quadrant or bell crank 'B fulcnumed at 3,8 and having a downwardly ex tending arm 39 with which two rods 40, 41 are pivotally connected. The rod 40 car :riesja cam head '42 lying in the path ofa wrist pins43 carried by a crank 44 on the shaft 45 which carries the main driving wheel '29.. The rod 41 has a terminal hook 46 also lying in the path of the wrist pin 43 which latter, be it understood, may be I equipped with an anti-friction roller 47.

The rods 40, 41 are .connected together by a coiled spring 48 tending to move the said rods in engagement with guide rollers shown at 49, 50. A trip member51 is provided for engaging a cam surface 52 on the vhook member 46 for the purpose of dis.

engaging said hook member from the wrist pin 43 at the proper time. Theother arm 5.3 of the bell crank B is connected by a link .54 with an arm 55 extending radially from the s aft .32, the connectionsbetween the ends of the link 54 and .the arms 53 and 55, respectively, being formed of universal joints 56' in order to enable the link to adapt itself to the movements of the arms 53 and 55. which operate in planes substantially at right angles to each other.

The ,paman 2.7 which actuates the main plunger rod 26 is provided with an anti friction roller 5,7. The rock shaft or fulcrum member 58 carries a bifurcated lever 59 having a relatively-long curved arm 60 carrying said apron are provided with convergent arms 65, 66 that combine to form driving brackets D, the apron-being provided at each side thereof with a guide lug 67, said guide lugs operating in grooves or 4 guide ways 68 iii the side walls 20'of. the

condenser chamber. The shaft 25 is provided with radial arms 69 which are conreception of'afresh charge according to the direction in tuated. I

An opening 71 for the admission of the which the rock, shaft .25 is ac division blocks between "the "bales is formed s in one side wallof the condensing chamber just above the press box. I

It is obvious that all the instrumentalities of the improved device are to be construct- 'ed,' proportioned, and arranged in such a Way as to operate in propersequence-and to cause the various steps ofthe operation to be properly timed. The operation in a general Way may be described as follows:

, With the condenser apron at the down ward limit of itsmovement, a charge of materialis placedon the apron orlwithin the condenser. When the condenser apron lsin this position, the plunger 30 will be locked at the lower limit of its movement, a charge of material having been projected within the baling chamber. When the main plunger head has traveled about one-third of the retracting stroke, the wrist pin 43 engages the Cam head42 of the push rod 40 whereby the bell crank 13 and related parts will be actuated to liftthe plunger, 30 to the upward limit of its movement. NVhen. the main plunger head has traveled about two-thirds of the retracting stroke, the roller '57 carried by the pitman 27 engages the long limb 60 of the bifurcated lever 59, causing the condenser apron ,to be moved in an upward direction, sweeping a charge before it beneath the. raised plunger 30] The wrist pin 43 now engages the hook 4'60f the billing rod 41 causing the bell crank B and related parts to be actuated to movethe plunger 30 in a downward direction, completely forcing theohargeinto the main bailing chamber adjzv cent to the main plunger head .26 which is nowpractica lly at the end of the retracting stroke. 'As the main plunger head starts on the .compression stroke. the roller 57 engages the short limb of the bifurcated lever 59., thus throwing the condenser apron opeirto receive another charge,

It Will be seenthat by the construction herein shown and described. a condenser of very large capacity 'is provided, this'being U to some extent due to the fact that thecondenser apron 1s carried by arms or levers instead of being hinged at its bottom edge. Much greater space for the charge is thus provided, and very bulky material such as straw and the like may be successfully baled. Owing to the large capacity of the condenser chamber, the same will also be easily filled or charged and the work may be done in a labor-saving manner. Each charge is forced completely down ahead of the main plunger, thus making neat square-ended bales, and not leaving a tag from each feed to go in with the next, thus tying the flakes of the bale together. But little power will be required for operating the press, there being expenditure of power for compression only and no loss from friction and binding, due to the charges being only partially forced down, as'is'the case with presses of thesocalled crane feed type. Excessive strains are eliminated for the same reason. The condenser stands open for nearly'half the stroke or complete to and fro movement of the main plunger head, thus giving ample time for the placing of the charge, this being a valuable improvement over other presses of the condenser type. The general construction is simple and inexpensive, andthoroughly practical and useful for the purpose for which it is intended.
